UW-REC (SHERIDAN): The experiment was located at the University of Wyoming, Sheridan Research and Extension Center in Sheridan, Wyoming during 2007. The soil, a Wyarno clay loam (fine, montmorillonitic, mesic; Ustollic Haplargid), had a cropping history of: 2006, fallow and 2005, small grains. The soil in the study area was prepared for planting by fall chiseling, followed by spring chiseling and roller harrowing. Twelve barley varieties were established in plots 5 by 20 feet using double disk openers set at a row spacing of 8 inches on 24 April. The seeding depth was 2.0 inches, and the seeding rate was 50 pounds of seed per acre. This location is a dry-land site with no irrigation. Rainfall during the growing period (1 April -31 July) was 7.42 inches. Subplots, 5 by 15 feet, were harvested on 7 August, using a Wintersteiger plot combine. |
